IP ranges are the different blocks of IP addresses advertised by an Autonomous System (AS). These ranges can be used by the same organization operating the AS, or by different organizations.

Peers of AS297

7 peers

AS293 AS2497 AS2914 AS6762 AS6939 AS20965 AS11537

AS297 peers with these other Autonomous Systems.

Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.

Upstreams of AS297

1 upstreams

AS209

AS297 uses these Autonomous Systems as its upstreams.

An upstream (or transit provider) is another AS that AS297 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.

Downstreams of AS297

6 downstreams

AS24 AS270 AS1848 AS10343 AS21556 AS393594

AS297 provides internet connectivity to these downstream Autonomous Systems.

A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
